wifi: ath12k: extend the link capable flag

Link capability categorized as Single Link Operation (SLO) and Multi Link
Operation (MLO).

 - Intra-device SLO/MLO refers to links present within a device
 - Inter-device SLO/MLO refers to links present across multiple devices

Currently, driver uses a boolean variable to represent intra-device SLO/MLO
capability. To accommodate inter-device SLO/MLO capabilities within the
same variable, modify the existing variable name and type. Define a new
enumeration for the link capabilities to accommodate both intra-device
and inter-device scenarios. Populate the enum based on the supported
capabilities.
